Development of Next Generation High Efficient Oil Cooler

Abstract

Newly Oil coolers with a highly efficient have developed using CFD and Experimental Study. Because in Engine lubrication sub-system, improvement of the efficiency, Pressure Drop Degree and High Heat Transfer are very important for vehicle fuel economy, environmental performance and next generation electrification system. The main core flow has eliminated from an oil passage, as a results heat exchange between a passage surface and an oil has performed in a temperature boundary layer without any fin devices. That oil cooler has both an increase in heat exchange and a suppression of pressure drop.
